Nanomedicine: A Vast Horizon on a Molecular Landscape – Part V, Nanoparticle Cancer Therapy
Nanoparticles, due to their unique structure, often possess an enhanced permeability and retention (EPR) effect. These particles can preferentially accumulate in tumors, resulting in higher drug concentrations at targeted sites and consequently higher therapeutic efficacy with lower toxicity for surrounding normal tissue. Also nanoparticle carriers can be designed to encapsulate and deliver cancer drugs having poor water solubility. These favorable characteristics render nanoparticles as promising potential delivery systems for cancer therapies.
